# Edexcel D1 - 17th June, 2016 [Exam discussion] watch

1. Anyone remember lengths of Prims questions individually, I know it's too much to ask but anyone ?
2. (Original post by AhnafR)
What did you get?
Can't quite remember, but it definitely asked for cost rather than capacity
3. (Original post by GusMick)
so the paper was bad, i didn't finish. Id say i skipped the last third of q7 and the last half of q8. Luckily a C on this and a decent ums on c3 and c4 should still see me getting an A overall. But idk if i even got a C on this
literally same i was hoping to get at least a B on this but dont even think i got a C :'( im actually relying on c3 and c4! need a B this year to get an A waahhhh
4. (Original post by pecora)
Has it been confirmed that 1.5y + x is (3y + 2x) correct?

Can anyone here please tell me if I will get follow through marks for putting 1.5x + y (3x + 2y)?
Not sure if you are wrong, but if you are you get ftM marks and one ftA( if there is two A marks)
100 UMS-75 maybe 74
A*-69-only because i got 69 lol.
A-59-it will not be any lower, no recent d1 paper was lower than 58.and there are harder past papers.
B-idk-i never get lower than this so i dunno.
6. Why is there no mark scheme for this crappy exam?!
7. I managed to complete that paper on time (barely) ....

but obviously got a **** ton of stuff wrong

Nah nevermind, I'll get 0. Does anyone remember how much was the linear programming question worth? Especially from objective line onwards?

Kinda rude ngl and you don't know that you've got 69
10. I did that whole paper in pencil, what happens if some parts dont get scanned? Can the examiner pull out the real paper?
11. Was there a question on dijkstras about finding a route via J ? Think I completely missed that question how many marks Is it worth ?

I think it was 80
13. (Original post by gekkelekkebekke)
can't remember but there were 2 critical activities happening around 12.5, along with 3 other activities hence minimum workers = 5
How can you have 2 critical activities happening at the same time?

But I agree at 12.5 there are 5 going on
14. For the simulatenous equation in the last question if you dont show any working out and just gave the answer do you get full marks? (I was running out of time so I used my calculator)
15. Does anyone know atleast when the paper will get leaked on TSR
16. (Original post by Person18)
People are saying they got 50 for the via J for D's algorithm, I think I got 49
I got 49 as well

It was 2 marks, one for the route and one for the length. I wouldn't worry too much about it now tbh, what's done is done
18. (Original post by Ilkonebi)
I got 49 as well
same. got 48 for first part and 49 for second

I would argue that the IAL papers are the harder past papers, not the UK ones, and I personally think this paper was harder than any of the UK papers. Boundaries will be slightly lower than last year, I would've thought.

100 UMS: 70/75
90 UMS: 63/75

Now for the important boundaries:
80 UMS: 57/75
70 UMS: 51/75
60 UMS: 46/75
50 UMS: 40/75
40 UMS: 35/75
20. 80 for prims is correct i believe?
